The ability to store event data in memory, upon event trigger occurrence, and transmit data
when desired.
•
The user can configure the MT-GL to store event-generated data, to be sent over the air to a
remote server, in its internal memory. This feature can be enabled or disabled using the
AT$MSGLOGEN command.
•
"Total Number of Unread Messages" is decremented if an unread message is read via the
AT$MSGLOGRD command.
Example: Assume there are 50 unread messages in the GPRS queue and the total number of
messages in GPRS queue is 100. This means that the first 50 messages have been read
while the last 50 messages have not been read. If a user sends AT$GPSLOGRD=0,1,51 then
the total number of unread messages drops down to 49 after successful transmission of that
message. However, if a user sends AT$GPSLOGRD=0,1,99 then the total number of unread
messages still remains at 50 – that message is transmitted to the remote server.
•
A user can also read a message that has already been read from the memory by passing in
the appropriate starting index number.
Synchronize RTC time with GPS time
•
RTC time is synched with GPS time automatically
•
RTC time is synched with GPS time every time the device is powered up and the device
acquires valid GPS data
•
RTC time is synched with GPS time every time the GPS time rolls over from 23:59:59 to
00:00:01
Allow a user to append RTC date and time at the end of event data
•
Bit-21 for Parm2, for output message types 40 – 42 & 45 (in AT$EVENT command), has
been added to allow users to send RTC time along with event data
•
The RTC date and time contains Year, Month, Day, Hour, Minute, and Second fields
•
6 bytes of information is appended in Binary format when bit-21 is enabled. Each byte
represents an individual field
•
12 ASCII character (12-bytes) representing RTC date and time is appended in ASCII format
when bit-21 is enabled. Two bytes (or two ASCII characters) represents an individual field
